Specification of Letters Patent.

Patented Feb.11, 1919.

Application filed February 15, 1917. Serial No 148,826.

To all whom it may concern:

'Be it known that I, CARL F. VERGEN, a citizen of the United States, residing at *Denver, in the county ofDenver and State of Colorado, have invented certain new and useful Improvementsin'Tools for Applying and Removing Antiskid-Chains from Tires, of which the following is a specification. 1

My invention relates to'a -tool-for applying and removing anti-skid chains upon and from pneumatic tires and has as its principal object to provide a tool of this character which is particularly adaptedto be used in applying and removing anti-skid chains which employ hooks that are ordinarily used on the Weed chains.

A further object of my present invention is to provide a tool of this type which may be constructed from a single bar of metal.

Another object of the invention provides an anti-skid chain applying and removing tool which may be effectively used toapply and'remove the chain with little physical effort. 7 7

Another object of the invention is to provide a tool possessing the above features and which consists of few simple cooperating parts which are formed from a single bar of metal and which can be manufactured anoil3 placed on the market at a minimum cos The above and additional objects will be set forth specifically in the following specification and the invention claimed therein.

Figure 1 is a fragmentary view showing one application of my improved tool.

Fig. 2 is a side elevation of the tool.

Fig. 3 is a rear elevation, and

Fig. 4 is a longitudinal sectional View.

My improved tool is constructed from a bar of metal which may be iron steel or other stout and nonbendable metal. In this instance the bar is illustrated as cylindrical but however it may be of any formation desired.

Referring to the drawing the numeral 5 designates a tubular bar of metal or shank of thetool. The upper end of the shank 5 is bifurcated or cut out as at 6 which provides spaced ears or wings 7. These spaced ears or wings 7 are integrally connected by a pin- 8 which is formed by the cutting out or bifurcating of the shank.

which are substantially V-shaped. The un der face of the obliquely extended portion is provided atits inner end'thereof with a recess or depression 12 which 1s for the purpose of accommodating the end of the connecting hook A. This depression provldes an outwardly extending shoulder 13.

The reference character A indicates a conventional form of chain hook which has its "body portion recessed in the usual manner to provide the hook members B and C. To fasten the chain, the tool is passed through one of the links on the end of the chain not having the hooks thereon and the pm 8 1s then engaged in the recess behmd the first hook member B. With the link as a ful crum the tool is swung so as to move the hook and link toward each other. In this connection it will be noted that as the pin 8 connecting the wings 7 is arranged to one side of the longitudinal axis of the tool, the wings 7 will engage opposite sides of the second hook member C as the tool is swung to approach this second hook member. Th s will bring the body portion of the tool 1n the same general plane with the end of the second hook member and will thus enable the link to slide along the tool and to be engaged behind said hook member.

Although not shown in Fig. 1 it is to be understood that the chain hook is to be provided with the usual pivoted keeper or guard member and when unfastening the chain the free end of this guard member is adapted to be received in the notch 11 of the opposite end of the tool and swung back to an inoperative position. The recessed portion 12 of this end of the tool is then engaged with the first hook member B so as to provide a fulcrum for the feet 10. These feet are arranged upon. opposite sides of the hook and extend forwardly beyond the second member 0 to be engaged beneath the link the latter being shown in dotted lines. The tool. fulcrumed upon the first hook member B is now swung to move the feet 10 outwardly along opposite sides of the second hook member C and as these feet are engaged beneath the chain link it will be seen that this link will be moved outwardly from the recess behind the hook member C and thus disengaged.

While the above disolOSure embodies the original idea of the invention it is to be understood that the same isca-pable of various modifications, alterations that may fairly fall within the scope of the appended claims.

What is claimed is:

1.- A tool of the character described -hav ing one end thereof bifurcated to provide spaced foot members and recessed adjacent said foot members to provide a fulcruming point.-

2. A tool of the character described, including a shank having one end thereof disposed at an oblique angle and bifurcated to provide spaced foot members, said angularly extended portion being provided at the rear of and intermediate said foot members With a recess providing a fulcrum point.

3. A 'tool of the character described, including a shank having one end thereof disposed at an oblique angle and bifurcated to provide spaced foot members, said foot members having not'ches formed in one edge thereof, said angularly extending portion being provided With a recess fanning a fulcruming point for the shank.

4. A tool for applying and removing antiskid chains including a shank having one end thereof obliquely disposed and bifurcated to provide spaced foot members, the rear end of said obliquely disposed end being provided with a recess, and a shoulder extending from the shank adjacent said recess.

In testimony whereof I aflix my signature in presence of two Witnesses.
